Definitions

  • the present disclosure generally relates to the field of antennas and, in particular, to an antenna housing for accommodating an antenna.
  • Antennas that are designed for outdoor use often include an antenna housing and an antenna assembly that is accommodated within the antenna housing. Outdoor antennas are often subjected to harsh conditions, and consequently the antenna housings are typically designed to meet specified waterproof performance levels and to be capable of resisting wind of certain strength. For example, base station antennas are often required to meet a waterproof rating of IP55 and to exhibit no visible damage when subjected to wind speeds of up to 241 km/hour.
  • a monolithic (single-piece) antenna housing such as an integrally-molded may have excellent waterproofing characteristics.
  • an integrally-molded antenna housing may also have certain drawbacks.
  • the back portion of the antenna housing may need to be made of a metal, such as aluminum.
  • the front portion of the antenna may need to be substantially transparent to RF radiation so that the antenna can transmit and receive RF signals. Consequently, if an integrally molded housing is used, it is typically necessary to provide a separate metal backframe that is inserted within the integrally-molded housing. Additionally, it may be more difficult to insert an antenna assembly into an integrally-molded antenna housing.
  • multi-part antenna housings that include two or more separate pieces.
  • an attendant problem is how to ensure the sealing and waterproof performance of such a multi-piece antenna housing while also ensuring that it withstand high wind speeds.
  • Providing a multi-piece antenna housing that meets stringent waterproofing and wind speed specifications can be especially challenging with respect to large antennas.
  • An object of the present disclosure is to provide a multi-piece antenna housing that is easy to assemble.
  • Another object of the present disclosure is to provide an antenna housing with high sealing and waterproof performances.
  • a further object of the present disclosure is to provide an antenna housing with sufficient windproof strength.

  • the front housing edge and the back housing edge are slidably engaged with each other.
  • the antenna housing defines a longitudinal direction, and the front housing edge and the back housing edge extend substantially parallel to the longitudinal direction.
  • the first sealing member is integrally formed with the front housing, and the second sealing member is integrally formed with the back housing.
  • the first sealing member and the front housing are made by pultrusion molding
  • the second sealing member and the back housing are made by extrusion molding.

  • the second sealing portion is formed with a second abutment surface
  • the front housing and the back housing contact each other merely through the first sealing portion and the second sealing portion.
  • the first sealing member is formed with an outer wall that extends from the first sealing portion, and when the front housing and the back housing are assembled, the outer wall is located outside the first sealing portion.
  • the second sealing member is formed with an inner wall, the channel being defined between said inner wall and the second sealing portion, and when the front housing and the back housing are assembled, a portion of the inner wall for defining said channel is located inside the second sealing portion and the channel.
  • the second sealing member is further provided with a stop element configured to prevent, after the front housing and the back housing are assembled, the front housing and the back housing from being separated in a direction different from the direction in which the front housing and the back housing are assembled.
  • the second sealing member is further provided with a reinforcing element configured to cooperate with the front housing to enhance the deformation resistance of the antenna housing.
  • the inner wall includes a first inner wall section, with the channel being defined between said first inner wall section and the second sealing portion.
  • the inner wall further includes a second inner wall section serving as the stop element and configured to prevent, after the front housing and the back housing are assembled, the front housing and the back housing from being separated in a direction different from the direction in which the front housing and the back housing are assembled.
  • the second inner wall section extends at an angle relative to the first inner wall section so as to at least partially cover the first sealing member.
  • the first sealing member is formed with a portion corresponding to the second inner wall section, which portion is close to the second inner wall section.
  • the inner wall further includes a third inner wall section serving as the reinforcing element and configured to cooperate with the front housing to enhance the deformation resistance of the antenna housing.
  • the third inner wall section is close to the front housing and extends substantially parallel to the front housing.
  • the first sealing member is formed with an insertion portion which extends from the first sealing portion, and extends into the channel when the front housing and the back housing are assembled.
  • the insertion portion has a cross-sectional shape substantially corresponding to a cross-sectional shape of the channel, and has a cross-sectional area smaller than a cross-sectional area of the channel such that a gap is formed between the insertion portion and the channel.

  • spatially relative terms such as “above”, “below”, “left”, “right”, “front”, “rear”, “high”, “low” and the like, may be used herein to describe one feature's relationship to another feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, features described as “under” other features would then be described as “above” the other features. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the descriptors of relative spatial relationships used herein shall be interpreted accordingly.

  • the inner wall 204 may include a first inner wall section 205 which, in the embodiment shown in FIG. 4 , extends generally in the front-and-rear direction from the body 22 of the back housing 20 toward the front housing 10. However, this is not limiting and the first inner wall section 205 may also extend from other locations of the antenna housing 1. For example, as shown in the embodiments in FIG. 8 and FIGS. 10 , the first inner wall section 205 may extend from the second sealing portion 201 toward the front housing 10 and may extend in a direction inclined with respect to the front-and-rear direction.

  • the second inner wall section 206 may be at a right angle with respect to the first inner wall section 205 in some embodiments.
  • the second inner wall section 206 may extend relative to the first inner wall section 205 to at least partially cover the first sealing member 101, thereby serving as a stop element to prevent, after the front housing 10 and the back housing 20 are assembled, the front housing 10 and the back housing 20 from being separated in a direction different from the direction in which the front housing 10 and the back housing 20 are assembled. For example, after the front housing 10 slides in place in the longitudinal direction with respect to the back housing 20, a blocking effect is generated since the second inner wall section 206 at least partially covers the first sealing member 101, preventing the front housing 10 from being separated in the front-and-rear direction with respect to the back housing 20.
  • the first sealing member 100 may be formed with a portion 104 corresponding to the second inner wall section 206.

  • the third inner wall section 207 may extend forwardly and may be positioned close to the front housing 10.
  • the third inner wall section 207 may extend substantially parallel to a side surface of the front housing 10. In the illustrated embodiment, the third inner wall section 207 extends substantially in the longitudinal direction of the antenna housing 1.
  • the front housing 10 When the antenna housing 1 is subjected to a transverse lateral wind, i.e. a wind load along the transverse direction, it is possible that the front housing 10, for example, may be blown inwardly and deformed.
  • the third inner wall section 207 may act as a reinforcing element, and hence the front housing 10, when deformed, will contact and abut against the third inner wall section 207; whereby the third inner wall section 207 prevents further deformation of the front housing 10.
  • the third inner wall section 207 serving as a reinforcing element cooperating with the front housing 10, the capacity of the antenna housing 1 in resisting transverse lateral wind or transverse wind load may be improved.
  • the first sealing member 100 may also be provided with an insertion portion 105, which extends from the first sealing portion 101.
  • the insertion portion 105 extends into the channel 203 of the second sealing member 200 and extends along the channel 203.
  • liquid such as water can be further prevented from entering the interior of the antenna housing 1.
  • liquid possibly passes through the interface between the first sealing portion 101 and the second sealing portion 201, due to the presence of the insertion portion 105, the liquid may not splash directly to the interior of the antenna housing 1 across the channel 203; instead, the liquid may be blocked by the insertion portion 105, enter into the channel 203, and may be discharged out of the antenna housing 1 through guidance of the channel 203.
  • the insertion portion 105 may have a cross-sectional shape substantially corresponding to a cross-sectional shape of the channel 203, and may have a cross-sectional dimension smaller than that of the channel 203.
  • the insertion portion 105 may have a cross-sectional area smaller than a cross-sectional area of the channel 203, such that a gap is formed between the insertion portion 105 and the channel 203. The gap thus formed can optimally block liquid and introduce liquid into the channel 203 to facilitate the subsequent discharge thereof.
  • the above description about the shape and size of the insertion portion 105 and the channel 203 is merely exemplary and not limiting.
  • the cross-sectional shape of the insertion portion 105 may be different from that of the channel 203.
  • the antenna housing 1 may be assembled by sliding the front housing 10 relative to the back housing 20.
  • the front and back housings may engage each other via a clearance fit rather than an interference fit.
  • the clearance fit is formed between the front housing edge 11 of the front housing 10 and the back housing edge 21 of the back housing 20.
  • only the first sealing portion 101 and the second sealing portion 201 may contact each other, which can reduce the friction during assembly and improve the assembling convenience of the antenna housing 1.
  • the first sealing portion 101 may serve as a slide rail
  • the second sealing portion 201 may serve as a slider.
  • the first sealing portion 101, the outer wall 103 and the insertion portion 105 may collectively form a substantially U-shaped slide rail, which facilitates sliding the second sealing portion 201 therein and facilitates the assembly of the front housing 10 with the back housing 20.
  • the portion 104 of the first sealing member 100 also extends at an obtuse angle with respect to the front-and-rear direction, i.e., is at an obtuse angle with respect to the body 12 of the front housing 10 and the insertion portion 105.
  • Such a design is advantageous during extrusion molding, since the obtuse-angle design facilitates the flow of the extruded material from the site of the body 11 to the portion 104 and further to the insertion section 105.
  • the antenna housing 1 further includes an end cap (not shown in the figures), which is engaged to the end portion of the front housing 10 and the end portion of the back housing 20 after the front housing 10 and the back housing 20 are assembled.
  • the antenna housing 1 may include a top end cap and a bottom end cap that are engaged to two opposite ends of the front housing 10 and the back housing 20 respectively, thereby forming a substantially closed housing with the front housing 10 and the back housing 20.
  • the bottom end cap may be provided with an orifice in fluid communication with the channel 203 of the second sealing member 200 so that liquid entering the channel 203 can be discharged out of the antenna housing 1 through the orifice in the end cap.
  • the antenna housing 1 is generally erected, i.e. its longitudinal direction corresponds to the vertical direction.
  • the channel 203 extends in the vertical direction; accordingly, after any liquid enters the channel 203, it can be discharged from the orifice of the bottom end cap by gravity via guidance of the channel 203.
